Description

Technical Field

[0001] This utility model belongs to the field of machining and relates to an end cap lateral positioning fixture and machining equipment. Background Technology

[0002] For example, Chinese patent literature discloses a precision-positioning motor end cap machining fixture [201620784547.X], comprising: a fixture body, a positioning groove formed in the middle of the fixture body, the size of the positioning groove matching the end cap protrusion, a positioning post E set at the center of the fixture body for positioning the spindle hole, machining holes A that match the position of fixing holes A respectively formed at the four opposite corners of the fixture body, and machining holes B that match the position of fixing holes B respectively formed on the outside of the positioning post E, wherein the diameter of machining holes A is larger than the diameter of fixing holes A, and the diameter of machining holes B is larger than the diameter of fixing holes B.

[0003] The drawback of the above technical solution is that during the drilling and milling process on the end cap, when the hole is close to the axial inner wall of the end cap, there is still a lot of room for improvement in its positioning, and the waste material from drilling and milling is not easy to clean at the same time. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing an end cap lateral positioning fixture and processing equipment.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] The end cap lateral positioning fixture includes a machine base;

[0007] The clamping frame includes a base connected to the machine base by a thread, a vertical rod vertically arranged on the base, a radially extending transverse rod on the vertical rod, an abutment block on the circumferential outer wall in the middle of the transverse rod, and a fastening block threadedly connected to the end of the transverse rod away from the vertical rod.

[0008] The clamping base includes two vertically spaced pressing blocks. The lower pressing block forms a limiting groove between itself and the machine base for the base to be embedded. The pressing block is provided with a strip-shaped positioning hole for the vertical rod to be inserted, and a cleaning nozzle is provided on the clamping base.

[0009] Furthermore, the base is disc-shaped, and the limiting groove has an arc-shaped edge that fits against the edge of the base.

[0010] Furthermore, the limiting groove is provided with a protruding positioning protrusion, and the base is provided with a positioning notch for the positioning protrusion to engage.

[0011] Furthermore, the vertical rod is provided with a stepped surface that abuts against the pressing block located above, and the upper end of the vertical rod is spirally connected to a pressing block that acts on the stepped surface.

[0012] Furthermore, the abutment block has a stepped shaft structure, and the end of the abutment block near the outer side of the transverse rod gradually tapers outward axially.

[0013] Furthermore, the abutment block has a positioning groove at one end near the outer side of the transverse rod.

[0014] Furthermore, the outer diameter of the abutment block gradually decreases inward along the axial direction of the transverse rod.

[0015] Furthermore, the outer diameter of the fastening block is larger than the maximum outer diameter of the abutment block.

[0016] This utility model also provides a processing device having the end cap lateral positioning fixture as described above.

[0017] Compared with existing technologies, this end cap lateral positioning fixture has reliable overall fixation, and the replaceable support frame increases its versatility. At the same time, the lateral clamping support frame is used to fix the workpiece to be processed, and the abutment block reduces the contact area of ​​the workpiece to be processed, allowing the end cap to be exposed over a large area. This avoids the problem of waste material adhering to the inner wall due to high temperature and the problem of drilling and milling displacement during the drilling and milling process, and also improves the cleaning and outflow of drilling and milling waste.

Detailed Implementation

[0022] Example 1, please refer to Figures 1 to 3This is a schematic diagram of an end cap lateral positioning fixture and processing equipment provided by this utility model. The end cap lateral positioning fixture includes a machine base 10, a clamping seat 30 disposed on the machine base 10, and a clamping frame 20 disposed on the machine base 10 and fixed on the clamping seat 30. It is conceivable that this end cap lateral positioning fixture also includes other functional components and specific structures, such as electrical connection components, control components, and installation structures, which are all technologies known to those skilled in the art, and therefore will not be described in detail here.

[0023] The clamping frame 20 is used to fix the workpiece to be processed and is detachably connected to the machine tool 10. The workpiece to be processed is an end cap structure. It should be noted that, in order to avoid the waste material from adhering to the inner wall due to high temperature during drilling and milling and to avoid the drilling and milling displacement problem, the flat surface of the end cap should face the side of the lathe to be processed before drilling and milling. In this embodiment, the workpiece to be processed is an end cap. The clamping frame 20 includes a base 21 that is threadedly connected to the machine tool 10. The base 21 is disc-shaped, and the outer diameter of the base 21 is much larger than other structures, so that the clamping seat 30 fits against the upper surface of the machine tool 10, and the center of gravity of the clamping seat 30 is close to the bottom. The clamping seat 30 is reliably installed and has stable force. A vertical rod 22 is vertically mounted on the base 21, serving as the vertical extension of the base 21. A radially extending transverse rod 23 is mounted on the vertical rod 22, serving as the transverse extension of the base 21. This design keeps the fixed end of the workpiece away from the main body of the clamping seat 30, avoiding interference during drilling and milling and interference during subsequent waste cleaning. An abutment block 24 is provided on the circumferential outer wall of the middle part of the transverse rod 23. The abutment block 24 is used for unilateral axial limiting of the end cap, reducing the contact area of ​​the end cap and exposing a large area of ​​the end cap for easier drilling and milling. In this embodiment, the abutment block 24 has a stepped shaft structure, with the end of the abutment block 24 near the outer side of the transverse rod 23 gradually tapering outwards. The middle part of the end cap has a mounting hole or a recessed mounting groove, through which the abutment block 24 is inserted into the middle part of the end cap. The outer wall structure of the outer end of the abutment block 24 is suitable for the mating and interlocking of mounting holes of different sizes. A fastening block 25 is threaded to the end of the horizontal bar 23 away from the vertical bar 22. The outer diameter of the fastening block 25 is larger than the maximum outer diameter of the abutment block 24. The fastening block 25 abuts against the outside of the end cap, forcing the end cap to be clamped between the abutment block 24 and the fastening block 25.

[0024] Ideally, a positioning groove 29 is provided at one end of the abutment block 24 near the outer side of the transverse rod 23. The positioning groove 29 allows the anti-foolproof protrusion in the middle of the end cap to be inserted accordingly, preventing the end cap from rotating circumferentially during drilling and milling.

[0025] Ideally, a padding structure can be provided on the outer wall of the outer end of the abutment block 24 to improve the fit and sealing of the middle of the end cap.

[0026] In this embodiment, the upper end of the machine base 10 is flat, and the clamping seat 30 is fixedly installed on the machine base 10. Specifically, the clamping seat 30 includes two vertically spaced pressing blocks 31. The pressing blocks 31 have a flat plate structure. The pressing block 31 located below forms a limiting groove 32 between itself and the machine base 10 for the base 21 to be inserted. The limiting groove 32 is provided with an arc-shaped edge 35 that fits against the edge of the base 21, so that the base 21 can be inserted horizontally and stably. After the base 21 is inserted stably, the base 21 is fixed on the machine base 10 by bolts.

[0027] The pressing block 31 is provided with a strip-shaped positioning hole 33 for the vertical rod 22 to be inserted. The strip-shaped positioning hole 33 is used for the two pressing blocks 31 to clamp and support the clamping frame 20 at two points, so that the support frame is stable under force. A cleaning nozzle 34 is provided on the clamping seat 30, and the cleaning nozzle 34 corresponds to the drilling and milling point position, that is, the circumferential outer perimeter of the pressing block 24. Optimally, the outer diameter of the pressing block 24 near the end of the vertical rod 22 gradually decreases inward along the axial direction of the transverse rod 23, which facilitates the outward flow of cleaning water carrying waste material and avoids the adhesion and residue of waste material.

[0028] The limiting groove 32 has a protruding positioning protrusion 36, and the base 21 has a positioning notch 26 for the positioning protrusion 36 to engage. By engaging the positioning protrusion 36 with the positioning notch 26, the support frame is prevented from rotating, ensuring that the milled surface of the support frame is accurately facing the machining equipment, thus improving the positioning effect of the support frame. It is conceivable that the support frame is a detachable structure, allowing for the machining of different end caps by replacing the support frame.

[0029] The vertical rod 22 is provided with a stepped surface 27 that abuts against the upper pressing block 31. An elastic pad can be provided on the stepped surface 27 to keep it stably attached to the bottom of the pressing block 31, forming a preliminary limit at the upper end of the vertical rod 22. A lower pressing block 28 is spirally connected to the upper end of the vertical rod 22 and acts on the stepped surface 27. The lower pressing block 28 is screwed into and abuts against the upper end of the pressing block 31, forcing the upper pressing block 31 to be vertically clamped against the clamping frame 20.

[0030] Example 2: This utility model also provides a processing device having the end cap lateral positioning fixture as described above. Except for the end cap lateral positioning fixture, all other components are existing technology or commercially available parts.

[0031] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
